• 
• 17%
• Created over 2 days

We counted 24 reviews for this product over the span of 1,251 days, an average of 0.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 1 or fewer reviews on any given day.

However, we see the following 2 days exceeding this threshold:

• 2 Reviews on Dec 27, 2019 (Avg. rating: 5.0)
• 2 Reviews on Dec 12, 2019 (Avg. rating: 4.5)

In total, we found that 4 reviews were created on just 2 days. This is an excessively high number of reviews submitted on these high volume days.

Take-Back Reviewers

• 
• 38%
• have previously deleted reviews

9 of the 24 reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, the discrepancy in ratings between the Take-Back Reviewers and reviewers who don't have any deleted reviews in their history isn't significant enough to rule out the possibility of it being due to random chance.

• Reviews have been deleted

We have not discovered any deleted reviews for this product.

There are a few limitations to keep in mind regarding the Deleted Reviews test:

1. We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
2. We have no information on reviews that were never published in the first place.
3. We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.
